My DC3 had got upset before tea tonight, she's had a runny nose and sore throat and when she's not feeling well her frustration can escalate quicker than usual. I think she got a bit hangry, and got in a state, crying and shouting loudly. She eventually came back to sit at the table but then got upset again (didn't want to wear a bib, wanted her food, didn't want her food etc). While she was crying loudly, DH who was sitting at the table shouted at her as loudly as he could, to tell her to shut up. That upset her even more and I asked him not to shout at her like that, and to go to another room. He did after a bit.
After DC calmed down and ate her tea, DH came back, and said his phone had alerted him that he'd been exposed to loud noise. I asked if it was her crying or him shouting at her, and he looked surprised that I was picking up on his shouting. He got defensive and asked if it was his fault, and I said that he shouldn't have shouted at her like that, and shouting at a toddler to shut up isn't right. He accused me of being selfish and not backing him up. We've disagreed over him shouting at DC before and I'd like to hear what others think about this. He's stormed out to go to a hobby without saying goodbye to us.
